Christina there is a book I LOVE. It's called Knitting in Plain English by Maggie Righetti. I used it to teach others (I taught myself to knit from books years back and this is WAY easier).
She wrote two others Crocheting in Plain English and Sweater Design in Pl. Eng.
I bought the set after I'd gotten to know the knitting book. I keep hoping to teach myself crochet sometime but that sweater design book is MARVELLOUS!
Later when you can knit (note I didn't say if) you will find out that commercial patterns are less than glorious. As Maggie points out this is not always the fault of the knitter.
She explains how to spot a faulty pattern, how to knit for yourself using your own measurements and all kinds of useful info.
but if you just get Knitting in Plain English out of your public library you can try it for free. If she doesn't "fit" well with you, you aren't out the cost of a book. (we are all different, and while I love her, it may be because she and I see things similarly so I understand her easily)
All the best!
